Equities dropped overnight amid concern about the glacial pace of progress in resolving Europe's debt crisis as there's still no agreement on a Greek debt swap, and bond yields in Portugal soared.
A European Union summit of leaders, the first of 2012, offered little hope as Germany's Angela Merkel said they won't finalise Greece's second rescue package today because talks with private creditors over lowering the debt aren't completed.
And in Portugal, borrowing costs soared amid concern that the nation's bondholders will be forced to take a big haircut, too.
"Some type of private-sector involvement for Portugal is a likely event and that is probably one of the key risks," Jim Cielinski, head of fixed income at Threadneedle Asset Management in London, told Bloomberg. "Portugal has been trading off quite markedly."
Wall Street fell as did Europe's major indexes, and the euro. In early afternoon trading in New York, the Dow Jones Industrial Average dropped 0.68 per cent, the Standard & Poor's 500 Index fell 0.66 per cent and the Nasdaq Composite Index shed 0.34 per cent.
